I wonder if anyone can help me because at the moment I have no idea where to start looking, so maybe here is a good place !
I have recently discovered proof to a story that my grandma has been telling me all my life ! that my great great grandma was the Marchese of StAgata, born in Naples in 1823, daughter of Prince Ruffano.Her name was Louisa B. Conolly (Luisa B. ??? in Italy perhaps ) after her marriage to Charles Thomas Conolly a prominent Irish businessman when they moved to England and lived at Midford Castle near Bath. Can anyone shed any light on who she was, who Prince Ruffano was, what was her family name etc. Apparently my grandma actually knew her but she is dead now and I have only recently got the urge to research this project. Hope someone can help me.

Thanks
